storchak [24]

Answer:

Area= 156ft^2

Step-by-step explanation:

Given

Two Rectangles;

Rectangle_1 = 12ft\ by\ 7ft

Rectangle_2 = 12ft\ by\ 6ft

Required

Determine the area of the shape

The area of the shape would be;

Area = Area\ of\ Rectangle\ 1 + Area\ of\ Rectangle\ 2

Area of rectangle is calculated as:

Area = Length * Width

For the first rectangle:

Area = 12ft * 7ft

Area = 84ft^2

For the second:

Area = 12ft * 6ft

Area = 72ft^2

So:

Area of the shape is

Area= 84ft^2 + 72ft^2

Area= 156ft^2

Can you guys help me
ra1l [238]

Answer:

x = 9

Step-by-step explanation:

9 to the sixth power = 531441

9 to the third power = 729

531441 = x cubed × 729

Divide by 729 on both sides.

531441 divided by 729 equals 729

729 divided by 729 equals 0

729 = x cubed

Find cube root

9x9x9 =729

Cube root of 729 is 9

x=9

Quick math question....

A

Step-by-step explanation:

In this problem, first u would have to keep the base of 3, then multiply the two powers together to get -28.
